pe2269 commented 1 year ago

Hi,

I bought two Atlas Scientific tri-pump (peristaltic) in order to connect them to a same RPI 4, Tentacle T3 and Mycodo. I tried to change the I2C address of the 3 pumps of the first tri-pump with mycodo but it return : Command returned: ('error', '2')

Versions:

Reproducibility

  1. [Go to output]
  2. add : Peristaltic pump : Atlas Scientific (I2C)
  3. set the default I2C adress (ex: 0X38), bus 1
  4. save
  5. New i2c adress : 0X28
  6. return in log :

How i could change the I2C address of this device ? (I tried with the Ezo : Raspberry-Pi-sample-code too) but same error too ...

Thanks in advance for your advice

Have you followed the documentation from the manufacturer?

pe2269 commented 1 year ago

Yes i think , the documentation concerning the changement of the I2C address is the same that the single Ezo Pump.

I think it's not a real mycodo issue but an Atlas scientific issue or mine .. :)

A solution was to change the i2c bus for one one the tri-pump ! They keep the same i2c address but not in the same bus ..

Ok it's my fault, you need to unlock the protocol lock with Plock,0 before changing I2C address.

Sorry for the opened issue

Where is that documented?

pe2269 commented 1 year ago

In the Atlas Scientific documentation of the EZO PUMP (not the TRI-PUMP) p72, it is written that the default protocol lock is 0. But in the case of the tri pump, Atlas scoezntific engineer answer me : "The protocol lock feature is enabled to prevent accidental address changes. Disable the lock, change the address, and then re-enable the lock. "
